I know, I know, you guys must be thinking: not another thread about the minion group rules! But I still had some thoughts on it after reading through previous threads and other google results that I wanted to share with you.
I understand the reasoning of combining low-level adversaries together. It forms a stronger unit that is harder to kill and it is easier to manage (one threshold pool and one attack roll). I also understand the rules, stating that the soak does not add up and one of the members of the group dies after the a single member's threshold has been exceeded. I have some great difficulties however to understand these rules from a mechanical and narrative point of view.
Let's use an example and compare 3 separate storm troopers versus a group from a mechanical point of view.
How much can they take:
When you have them work separately, they all have separate soak values/wound thresholds. This makes it very hard to take them down because you have to do 3*(wound threshold + 1 + soak) worth of damage. You will also be inefficient, because you might have extra damage on one storm trooper that is lost, because he's already down. So for storm troopers with 5 WT and 5 soak this makes a minimum of 33 damage. When they are together however, you can hit them all at once, only counting the soak once. You will be very efficient, because you can damage more than one storm trooper at a time, and even add 5 wounds for a critical hit. The minimum damage is reduced to 1*(3*wound threshold+1+soak), which is 21 in our example. It is much lower than the previous minimum and on average you will even be much closer to this minimum than in the other case.
How much damage can they deal:
Storm troopers that attack separately will do, if roll is successful, 3*(base damage + successes). When together they only do 1*(base damage + successes). Although the roll is upgraded in this case, so that there is a higher net result of successes/advantages, I think the net damage/advantage will still be lower in most cases.
From a narrative point of view this makes it really difficult for me to understand why minions would group up in the first place. It's logical that you are close and in formation, you are more likely to be hit. This is reflected in the mechanics, by only using one soak value. However, it would seem logical to me that their attack frequency would remain the same and the average damage dealt would go up. This, it seems, is not reflected in the mechanics. You have one attack with on average more damage than a single attack of one minion, but the average damage in total goes down. Would't it be better to have them add up their attacks, and give them a boost die on top or something?
Another narrative aspect that bothers me is when damaged minions would want to team up. Suppose you have 3 separated storm troopers that have 3 wounds each. They want to team up to increase their chance of success or make a final stand. By using the group rule, they will become weaker, first because the damage they can deal and take goes down, but on top of that one storm trooper will suddenly die because the total wounds exceed the wound threshold of one storm trooper.
I'm very interested to hear your thoughts/comments on this.
